VALVE-SPRING COMPRESSOR.

Application filed September 18, 1922.

This invention comprehends the provision of a valve spring compressor, and aims to provide a tool by means of which the spring can be conveniently and easily compressed and held in this condition while bein inserted in the motor, and the opposite ends of the spring alternately released after the valve has been placed in position.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawing, the invention residing in the construction, combination, and arrangement of parts as claimed.

In the drawing forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a view of the tool forming the subject matter of my invention.

Figure 2 is a view showing the manner of compressing the spring.

Figure 3 is a View showing one of the difterent positions in which the jaws may. be ar- 1" ranged with respect to the handles of the tool.

Referring to the drawing in detail, 10 and 11 indicate a pair of crossed pivoted handles,

the corresponding extremities 12 being arranged substantially parallel. Supported by these parallel extremities are spaced pairs of pivoted jaws, the jaws of each pair being indicated at 13 and crossed as shown. The jaws are connected to the extremities 12 by means of a pivot 12 which not only permits relative movement of the jaws of each pair with respect to each other, but permits the jaws as a unit to be arranged at any desired angular position with respect to the handles as illustrated in Figure 2. It is sometimes necessary to arrange the jaws in dilieren't positions with relation to the handle, depending upon the particular place in which the jaws with the spring is adapted to be inserted. The tool is intended to compress and lift the spring incident to the separation of the valves from the motor, but is Serial No. 588,986.

merely designed to compress the spring prior to the replacement of the spring, within the motor, and to permit the spring to be conveniently released. In practice, the spring is arranged between the spaced pairs of jaws, after the latter have been adjusted to accommodate themselves to the particular diameter of the spring being dealt with, and

then the handles are brought together to compress the spring as will be readily understood.

The spring is held in this condition while it is being insertedin the motor in its proper place, after which the valve is inserted. The jaws of the upper pair are then separated to release the upper end of the spring, and then the jaws of the lower pair are released for the same purpose. Any other convenient tool may be subsequently used to compress and lift the, spring while the cotter pin is being inserted in the stem of the valve. The tool is not only simple in construction, but is very handy and convenient for the purpose otcompressing the spring and inserting the latter within the motor in a compressed condition.

While it is believed that from the foregoing description, the nature and advantages ot' the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

hat I claim is I A spring compressor comprising a pair of pivoted crossed handles, having their corresponding extremities arranged in planes at right angles to said handles, a pair of pivoted jaws supported on the outer side of each of said extremities and pivotally associated therewith to permit said members. to

be swung upon their axes in planes at right angles to said handles and to occupy any desired angle with relation to said extremity. In testimony whereof I afiix my signature.
